Hidden fees and NO refund: avoid this service!
I went just one minute over my call allowance and immediately received a bill of nearly €40—with no prior warning that my minutes were running out. I only discovered it the next day. Absolutely outrageous!
I contacted the company, expecting some understanding or goodwill, but they refuse to issue a refund. This is completely unacceptable.
Do not subscribe to this service. They charge hidden fees and show zero customer care.
I request a refund for this criminal charge.

Okay provider, but greedy monetization schemes.
Okay provider otherwise, but in my opinion it's predatory to charge for a data limit. Do not trust them to keep your best interests in mind. My wife turned off her data as soon as she got a notification that she was over her bundle, and now she's paying a significant portion of the monthly cost for the measly 56 megabyte of data that she went over. If you don't want it to happen, you have to pay them an extra charge monthly. I'm sure that technically, this doesn't cost them anything. Seems like a bit of a protection racket.

Hi Pepijn,
Thank you for your review.
We understand that unexpected charges can be frustrating. At Simyo, we work with a clear bundle structure: if you use more data than your bundle includes, out-of-bundle charges apply. To help prevent this, we offer the feature of setting a data limit. This option is available so customers can choose what best fits their needs.
If you would like us to take a closer look at this situation, feel free to contact us at webcare@simyo.nl

Hi Vico,
Bedankt voor je review. Fijn om te horen dat je bereik goed werkt in Nederland!
Als je in het buitenland bent, is het soms zo dat je handmatig een netwerk moet selecteren in je telefoon voordat je verbinding werkt: https://www.simyo.nl/klantenservice/toestelhulp/netwerk-handmatig-selecteren.
Mocht dit geen verbetering hebben opgeleverd, neem dan gerust contact met onze klantenservice op. Wij helpen je dan graag verder hiermee!

Good quality, good prices
I've been a Simyo customer for about 10 years. Quality is very good, user experience has been steadily improving as well. Prices are great too.
The only downside is the rather complicated system of accounts and contracts. I just ordered a new number, for my daughter. She just needs a number for now, no mobile internet and almost no calling. I ordered prepaid. While ordering, Simyo told me we can get 10 euros each if we make up a family. We do, so I tried. Nope, it turns out you can only get family account if you order Sim Only, not Prepaid. Not only can I not get that 10 euro discount for each of us (but they did promise 5 euros off the first invoices, let's check), but I cannot manage her contract either. I hope I didn't misunderstand them. But if I did, it only proves my point ))

Hi Konstantin,
Thank you for your review.
We are happy to hear that you've been a loyal customer for so long and that your experience with us keeps getting better. This is what we do it for!
In your review, you mention our "Vriendendeal". You will only receive a €10 discount if both you and the new customer have a Sim Only plan. If one of you has a Prepaid connection, the discount will be €5 per person. So you and your daughter are indeed eligible for a €5 discount. 🙂
You can find more information about this on our website: https://www.simyo.nl/vriendendeal

An absolute scam !!! €116,68 for 786 MB !!!
An absolute scam. They billed me €116,68 for 786MB I used above my current plan. Yes, that's megabytes, not gigabytes!
They seem to charge €0.15 per 1MB for data overage, and they don't cap your usage by default. To enable the capping, you need to pay €0.50 per month for a very basic functionality.
I'm eligible to KPN Compleet which would have given me 20GB instead of 10GB, but that was never activated by them, because their system is not detecting that I'm eligible. Talked to their customer support and besides "Try again", they were of no help.
In short, it's a scam. It's designed to make you endure these super high charges (I wonder if that's their main revenue stream)
!!! €116,68 for 786 MB !!! What world are these people living in.
I'm looking forward to the end of my contract so I can switch to another provider.

Hi Ilyas,
Thank you for your message. We are sorry to hear about your negative experience.
We always send two warning text messages if your internet bundle is (almost) finished. One when 80% of your internet bundle has been used and one when the internet bundle is 100% used. The last message informs you about the rate of € €0.15 per MB. It also lets you know that you can decide to add an extra bundle or to turn off the mobile data on your phone to avoid costs outside the bundle. Have you seen these messages? We block your SIM card as soon as you have incurred high costs within a short period of time to prevent the costs from running even higher.
We would like to view the subscription with regard to the costs outside your bundle and Simyo Compleet. Could you e-mail us to webcare@simyo.nl with a reference to this review? We would love to help you further.

Simyo Webcare
Not privacy minded
Weird that you can anonymously buy a simcard in a store, but for an e-sim they want all your personal data.

Terrible company
Terrible company. Whilst disputing an interest payment when Simyo only attempted the payment once and speaking directly to their customer support team they preceded to double the fee.
Outrageous practises and no trust in this business. Avoid.

Scammers more than service providers
The key is that Simyo’s focus is to maximise revenue, not to optimize customer satisfaction.
Simyo attracts customers by offering competitive packages with limited data access within EU and no allocation outside EU. Exceeding the limits will lead to exorbitant charges, like 500 Euro in 8 minutes data usage at the airport in a non-EU country, 2,000 Euro for usage outside package of a few GB in data within EU.
This is in no relation to any actual cost made (10GB within package is charged 2 Euro, excess charge for 10GB is more than 1,000 Euro).
The result is a very unreliable provider, a company you basically do not want to deal with as it makes you feel they are after finding ways to “get” you.

Hi Rien,
Thank you for taking the time to share your experience with Simyo. We’re truly sorry to hear about the difficulties you encountered with our data packages and charges. Our intention is never to cause frustration or make our customers feel uncomfortable, but rather to provide clear and competitive options.
We understand how unexpected charges, especially when traveling outside the EU, can be alarming. We strive to be transparent about our data limits and fees, and we encourage customers to review the terms carefully before using data abroad. That said, we value your feedback and will take it into account as we continuously work to improve our services and communication.
If you’d like, please reach out to our customer service team directly so we can assist you further and see if there’s a way to resolve your concerns.
Kind regards,
Simyo Webcare
very limited and every little thing costs extra cost.
I’m really not happy with Simyo. Everything feels very limited and almost every little thing seems to come with an extra cost. One of the most frustrating things is that the moment I cross the border into Germany or Belgium, my mobile data stops working completely. I immediately receive a message saying I need to pay extra to use data, which was a huge disappointment.
I genuinely believed that Simyo would work throughout EU Zone 1 without issues, as most providers offer this by default. Unfortunately, now I realize that going for the cheaper option wasn’t worth it in the long run. As soon as my contract ends, I’ll definitely be switching to another provider

Hi Ramon,
Sorry to hear you're not happy with Simyo, that's definitely not the experience we want to provide.
Regarding your mobile data abroad: within the EU, you should normally be able to use your bundle just like you would at home, without any extra charges. If you're receiving a message about additional costs the moment you cross the border, you might have run out of data on your normal bundle. I would be happy to look into it for you to know for sure what happened.
Feel free to reach out to us at webcare@simyo.nl, and we’ll gladly help you sort it out.
Kind regards,
